digitalmars.D - is this a dmd bug ?
- Long Chang (15/15) Nov 24 2009 public interface Listener {
- Denis Koroskin (7/23) Nov 24 2009 Try removing a dot before print.
- Steven Schveighoffer (4/20) Nov 24 2009 It's the . before the print. It means "only look in the global scope".
- Long Chang (22/22) Nov 24 2009 how about this case:
- Steven Schveighoffer (9/33) Nov 24 2009 Try outer.toString(evt).
- Long Chang (8/8) Nov 24 2009 I use the d1 & tango trunk & dwt-win.
- Denis Koroskin (6/15) Nov 24 2009 Try using older version of Tango (before introducing Object.dispose()
- Steven Schveighoffer (31/40) Nov 24 2009 Hm... I've noticed that you can't just call outer, you have to use
- Long Chang (2/2) Nov 24 2009 this.outer also. work on d1.
public interface Listener {
void handleEvent (int);
}
void main(){
void print(int evt){
}
Listener listener = new class() Listener {
public void handleEvent(int evt) {
.print(evt);

};

Try removing a dot before print.
As is, it searches for a print function at a global scope, fails to find
one and shows an error.
I'm not sure it is a proper behavior, though. Try creating a bugzilla
report.

how about this case:
public interface Listener {
void handleEvent (int);
}
class Test{
this(){
Listener listener = new class() Listener {
public void handleEvent(int evt) {
toString(evt);
}
};
}
void toString(int evt){
}
}
void main(){
}

Try outer.toString(evt).
Note that the anonymous class inherits from Object, which defines toString
as:
char[] toString();
So the compiler thinks you are trying to call your anonymous class'
toString, not the outer class' toString.

I use the d1 & tango trunk & dwt-win. there is a new dispose method for Object, and Dwt-win already have a dispose width Event argument. I try it with outer, the error is : x.d(17): Error: undefined identifier outer x.d(17): Error: undefined identifier outer x.d(17): Error: no property 'toString' for type 'int' x.d(17): Error: function expected before (), not 1 of type int

It's not a DMD but, it's just DWT is incompatible with Tango trunk at the moment (due to a breaking change in Tango).

I've noticed that you can't just call outer, you have to use this.outer. Does anyone know if this is expected behavior or a bug? Why would it be expected behavior? This code compiles for me and works on dmd 2.033 import std.stdio; public interface Listener { void handleEvent (int); } class Test{ Listener listener; this(){ listener = new class() Listener { public void handleEvent(int evt) { this.outer.toString(evt); } }; } void call() { listener.handleEvent(0); } void toString(int evt){ writefln("event is %d", evt); } } void main(){ (new Test()).call(); } -Steve
